First stage

Child Assessments for cochlear implantsYou and your child will be seen by a consultant and other members of the team in a children’s cochlear implant centre. The centre will usually have asked you to complete a preliminary questionnaire with some basic information about your child. The centre may have asked your permission to approach your child’s doctors, audiologists, teachers and other professionals involved with your child for information.

Your child’s hearing will be assessed in detail. It is very important to make sure that every child has had the best possible hearing aids and earmoulds, and has used them consistently before proceeding with decisions about cochlear implantation. The child’s teachers and local therapists may also be asked to comment on the child’s auditory progress.

These initial visits may last for most of the day as there can be a lot of work to do.

Some children may be found to be unsuitable for an implant as assessment progresses. Cochlear implant centres will ensure that everyone understands clearly why the decision against cochlear implantation was made, and will offer the opportunity for alternative ideas to be explored.

Second stage

This involves detailed assessment at home and at school, and a named key-worker will help co-ordinate this and provide a contact for you. As well as visits by the cochlear implant team members to home and school, there will be assessments of language, communication, education and expectations by the advisory teachers, speech and language therapists and psychologists.

Certain specific tests will be important for most children.

A CT scan which is a specialised X-ray of the inner ear is carried out to establish whether it is possible to insert a cochlear implant electrode into the cochlea. It is often followed by an MRI Scan (Magnetic Resonance Image). The MRI will look carefully at the soft tissues, and the nerve of hearing.

Auditory Brainstem Response (ABR) tests may also be required. This is a hearing test using temporary electrodes placed on the head to pick up the responses to sound.

The CT scan, the MRI and the ABR are all painless, but do require the child to be completely still. It is for this reason that a short general anaesthetic, given by a specialist children’s anesthetist is sometimes necessary. Most children under the age of six years will require an anaesthetic.

Some children may require additional tests which will be discussed with you.

This second stage can take quite some time to complete, especially if the child is asked to try a different type of hearing aid which can lengthen the process. You will be in close contact with your keyworker who can inform you of how the various parts of the assessment are being organised.

Finally, there will be a meeting of the children’s cochlear implant team at the end of the assessment period. Whether or not the team consider a cochlear implant to be the best option for your child will be discussed, and if an implant is offered, then you have plenty of time to consider your decision.
